Question

Which nerve is tested for adequacy of anaesthesia ?

• A. Median Nerve
• B. Ulnar Nerve
• C. Radial nerve
• D. Mandibular nerve

Answer 1

The Correct Option is A

In the field of anaesthesia, assessing the adequacy of anaesthesia is crucial to ensure that the patient experiences neither pain nor discomfort during surgical procedures. There are several methods used to test anaesthesia adequacy, and among the peripheral nerves, the Median Nerve is commonly used for this purpose.

The Median Nerve runs through the arm and is responsible for sensation in part of the hand and specific motor functions. Adequate anaesthesia of the median nerve is indicative due to its encompassing coverage and easy accessibility.

To test the adequacy of anaesthesia, anaesthesiologists may perform a sensory examination to ensure loss of sensation in the areas innervated by the median nerve. This often involves checking for numbness or a lack of response to stimuli in the palm of the hand and the first three fingers. Ensuring the median nerve is adequately anaesthetized helps ascertain the surgical region's numbness and thus, confirms that the anaesthetic has taken effect appropriately.
